Error is reported when "from py4vasp import Calculation" in jupyter

[xinliang-huang]

Hello,

I install py4vasp, and then run the command "python - c" import py4vasp; print (py4vasp. version) ". It indicates that the installation is successful, but an error is reported when running in jupyter. I don't know why.

After running "from py4vasp import calculation", an error is reported as follows：

Output exceeds the size limit. Open the full output data in a text editor

Thank you for reporting this. The issue is caused by a recent upgrade to ipywidgets that broke the nglview package. To fix this you can

pip uninstall ipywidgets
pip install ipywidgets==7.7
